Hey I've noticed when turning right over bumps that my truck makes a scraping sound on the right side near the middle. I haven't been able to get anybody to check it out and see what It's hitting but I was wondering if this is a common thing? I have a 4" diamondeye btw which i think is what's scraping.

 

If its happened a few times already, you should be able to look for a shiny spot for where the tire or what have you was rubbing.....

My old ford had a 2" polished strip on the radius arms from where the tires would rub.

 

It doesn't really sound like the tire hitting is the thing. I've heard things about the bed hitting the cab corner when flexing. Does anybody know anything about that?

 

I'm not sure who says that, but I have never been aware of any flex, at all. Maybe your body mounts are shot...Mark

 

I've seen lots of first gens where the box corners hit the cab, I had to fix my '93 when I painted it. That being said it doesn't occur in daily driving but when off road or in a situation where the frame is flexing (one front wheel up opposite rear wheel down sort of thing).

 

I'v had mine on some pretty rough trails and I have never been aware of any flexing in the truck. It is a pretty stout frame. I am not saying that it doesn't happen, just that it doesn't happen to me...Mark

 

I don't think the frame will flex enough on 91 up for the bed and cab to hit. 89-91 had a little less frame and might. I promiss a 1/2 ton will hit. That said the cab dimples from that are a good indicator the trucks been beat up offroad even in a 1/2 and should never happen in normal driving.

 

I would get under the truck and check the bed bolts and cab corner bolts and make sure they are tight. Maybe one of them have/has worked loose over the years.
